LUMBER-PILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 570,868, dated November3, 1896.

' Application filed September 10, 1895. Serial No. 562,066. (No model.)

To all whom it may concern:

Be it known that I, HOWARD DANIELS, of Atlanta, in the county of Fultonand State of Georgia, have invented a new and useful Improvement inLumber-Filing Machines, of which the following is aV specification.

My invention is an improved lumber-piling machine, and relatesparticularly to that class of such machines wherein the lumber is piledon edge, and the present invention is an improvement upon the machinecovered in my former patent, No. 500,86l,dated July 4, 1893; and theinvention consists in certain novel constructions, combinations, andarrangements of parts, as will be hereinafter described, and pointed outin the claims.

In the drawings, Figure 1 is a perspective View of my improved machine.Fig. 2 is a side view thereof. Fig. 3 is a detail view illustrating thedevices for binding the load. Fig. et is a detail View of the mechanismfor holding the stakes up to the load. Fig. 5 is a detail view of one ofthe hooked stake-rings. Fig. 6 is cross-sectional View of the machine.Fig. 7 is a detail view thereof. Figs. S and 9 are'detail views of thestake-feeder. Fig. lO is a detail view of the cam, and Fig. ll is apartial vertical cross-section of the apparatus.

The framing may be similar to that employed in my said former patent.The swinging conveyer-frame A is hinged at a, and is arranged to lowerto position to receive the lumber from the chute AB and to lift thecourses of such lumber successively to position upon the truck O, whichtruck may in general respects be similar to that employed in my saidformer patent.

The connection between the swinging frame and its operating gearing isjoined to said frame at a point above the pivot-point of such frame,because it affords a stiff and effective arrangement of the parts.

In operating the said frame I connect it by pitmen A' with cranks A2 ona shaft A0. This shaft, as shown most clearly in Fig. ll, supports thenotched or cam pulley F and has a gear-wheel A4 on a drive-shaft A0,such shaft having a clutch-section A7, by which the pinion A5 may bekeyed to the shaft or freed at will. This clutch is operated by aswingi'ng arm A8, connected by a link A0 with a swinging arm A10,Whichis pressed against the cam F and into the notches f thereof by a springA11.

In operation, the shaft A0 turning continuously, the arm A10 when in theposition shown in Fig. ll will, by parts A8 and A0, hold the clutch A7in engagement with the pinion A5, and the shaft A3 will be caused toturn so long as the arm A10 remains in the position shown in Fig.ll,which will be until one of the notches f comes in line with the armA10, when the latter will be drawn by the spring A11 into the notch andthe shaft A3 will cease revolving until the arm A10 is again adj ustedto set the clutch A7 into engagement with the pinion. This may be`effected by the pull-cord A12, which may extend within convenient reach0f the operator, so that when the shaft A3 and the swinging frame A areat rest with the frame A in either its upper or lower position theoperator may set the shaft A3 in motion by drawing upon the cord A12.

The parts A8, A0, and A10 and the cord A12 may be similar tocorresponding parts in my former patent, but in the present case I makethe cam with two notches, so the frame A can be stopped in bothpositions.

The retarding-timbers D operate similarly to the corresponding parts ofmy former patent, but differ therefrom in form, being tapered or slopedat d above the chute to form a flaring inlet for the boards sliding downonto the conveyer-frame.

In the use of my patented machine it has been found that theseparating-stakes are not always sufficient to hold the courses up inVertical position while the conveyer-frame is returning to receiveanother course.

To properly support the courses, I provide the pile-retaining bar E,which is movable into and out of position in rear of the lumber pile asthe successive layers are applied, and 1 to afford time for the movementof the bar E into operative position I provide the cam F IOO point where.it is down in line with the chute. This holds the course of lumber inthe vertical position until the traveling bar can be run up to hold thecourse while the next course is being collected. This bar It moveslongitudinally in a vertical direction, being held at its lower end insuitable guides E', while its upper end moves through a guide-opening E2in the framing, such opening E2 being elongated to permit alimitedback-and-forth play, the upper end of the bar E resting back of a stopE3 when such bar is in its extreme uppermost position.

The bar E drops by gravity, and to properly set its upper end whenlowered so it will on its next upward movement adjust properly alongsidethe last-applied course o f the pile I provide a yielding presser G,which is arranged adjaeent to the path of the bar and operates todeflect the same when moved downward from alongside one course toposition to move alongside the next course when the latter has beenapplied. In the construetion shown this presser G is preferably a lcverpivoted at g between its ends, having a roller g at one end to bearagainst the bar E and having a weight g2 at its other end operating toset the .roller against the bar E in such manner as to set the said barin position to rise alongside the last-applied course.

To lift the bai-EI provide in connection with the drive-shaft II, fromwhich the whole machine derives its motion, a paper frictionpulley lI,below which is an iron friction-pulley I on a shaft I2, which shaftcarries a spool I3, from which a chain or other connection Il extends upover a sheave I5 and thence connects with the bar E near the lower endof the latter. NVhen the shaft I2 is turned by the bearing of itsfriction-pulley I against the pulley II, the bar E will be raised, andwhen such pulleys II' I are out of contact the bar will fall by gravity.To this end the shaft I is supported at its end adjacent to the pulley Iin a sliding box fi, so the pulley Il can be set into or out of contactwith pulley II, the movements of the shaft being effected by means ofthe lever J, connected With the operator-s rod J.

To hold the bar in elevated position until it is desired to lower it, aconcave brake K, lined with leather or the like, is arranged beneath thepulley I, so that when released from bearing against pulley II suchpulley I will drop into the brake and prevent the spool from unwindingand holds the bar E at any height desired. To let the bar drop, thepulley I is raised out of the brake, but not enough to bring it intocontact with the friction-pulley ll. In operation the barE is left upwith its top behind the stop E3 until a new course of lumber is broughtup by the frame A. This pushes the truck ahead and the swinging framestops. The bar E, being now between two courses, is dropped by theoperator, `is pressed by the yielding presser G back so it will pass upback of the last course until its topl sets back of the stop E3, asbefore, when the frame A can be lowered for another course. In thisoperation as each layer of boards is moved, upward by the eonveyerframethe latter also moves up with it the stakes which separate such layerfrom the following one, and these stakes are held in place by the strainof the boards on the truck acting against the latch overhead and therock-shaft on which the conveyer-frame is hung below. As theconveyer-frame rises to a perpendicular position the stakes carried upthereby work downward, so that their lower ends rest on the top of thetruck which holds the load of lumber, and in reaching such position theAlower ends of the stakes come in behind the said rock-shaft and theirripperA ends are caught by the latches. Then the strain of the boardsholds them in place until the next course comes up. This strain isoccasioned by the weight mechanism that tends to pull against the loadat bottom and top.

The parts E* serve as stops for engagement by the plate E5, secured tothe bottom of the bar E to limit the upward movement of the said bar.

The stake-feeders L L are arranged one at each side of the swingingframe A, and comprise side beams L', which incline upward to the levelof said frame A when the latter is in lowered position. These beams Lhave mortises Z to receive the sprocket-wheels l\I and grooves Z" toreceive the chains Im running on said wheels. The chains m are carriershaving lugs m every second link. The wheels M are on shaft M', and onthe lower end of the upper shaft N is iiX'ed a ratchetwheel N. Apawl-earrier O turns on this shaft and has a pawl O' engaging the wheelN, a portion O2 to engage a stop on the feederframe, and a point orportion O3 for engagement by the conveyer-frame, the latter preferablyhaving a lug O4 to engage the portion O3, as shown. The spacing-stripsbeing placed on the lugs of the chains,the movement of the frame Aimparts a step-by-step motion to thc said chains through the mechanismdescribed, and the stakes are fed oneat a time up to the tops of thefeeders, where they pass through notches p into the rest-plates I),which latter may be similar to corresponding parts in my former patentand need not be described in detail. By this construction of feeder thestakes are fed positively to the swinging conveyer-frame.

In practice it has been found that the stanchions shrink more or less ingoing through the kiln, which gives them a little play and tends toallow the top of the pile to open in the process of loading and letboards get into the spaces so formed. To avoid this, I provide thetension devices consisting of the shafts Q and Q, havingsprocket-chains, bearingstops Q2 to receive the ends of thetruck-stanchions, and to the shaft Q is fixed a spool,

from which a cord q, having a weight q', is disposed over suitableguide-pulleys, so the stress of such weight will operate against thetops of the stanchions, keeping the load snug and tight all the time. l

To bind the pile when loaded, I provide malleable-iron rings R, adaptedto fit the rounded ends of the stanchions and have projecting hook-likelugs R.

Levers S are pivoted at S on the overhead timbers directly over thetruck and have connected chains S2, provided with hooks S3 to grasp thestanchions. By this lever mechanism the stanchions may be drawn tightlytogether and secured by trace or other chains put across the top andlinked to the hooks R of the rings R. Y To quickly run the load out ofthe machine, I provide in practice a shaft T, having a pulley T', whichcan be set into contact with the pulley II', and a spool T2, from whicha line can be run over suitable guides and connected with the truck.

I do not desire to limit myself to the exact framing shown, as differentlocations may render changes necessary, and this applies to the locationand connection of the workmans levers.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
